Most machines end the current day at noon, but then any sleep done after noon is combined with what you did that night. Missed this bit. That might be part of my problem. I sometimes check the info in the afternoon, and recently I have been three time zones west of home, so perhaps it is resetting ...

I am newly arrived here because I'm having the same problem with the same equipment, I think. I just started treatment with this machine and mask combination, picked it up December 23, started using it December 29, and I have been pretty faithful since then, maybe 4 nights when I haven't tried to us...
